Hello MADlib folks, I was testing MNIST dataset with minibatch preprocessor + MLP on master, and could not get it to converge. It turned out to be user error (me) and not a problem with convergence at all, because I forgot to 1-hot encode the dependent variable.
But I am wondering if other people might do the same thing that I did and get confused, so I created 2 JIRAs that I hope will help out: https://issues.apache.org/jira/browse/MADLIB-1226 https://issues.apache.org/jira/browse/MADLIB-1227 I'd suggest we do this for the upcoming release 1.14. Please let me know if you don't think this is the right approach. Frank
